eh, bayonette isnt anything special. it is just the same as knifing but with the actual gun. no different mechanics involved. sticky grenades...sure that is new and kinda neat. molatovs fuckin suck suck suck. gas grenades do the same thing the flash bang did in 4 for the most part. meaning they incapacitate you for a short period of time. vehicle perks are only there and new because well, cod4 didnt have vehicles. flame thrower is bleh. the only thing i do like is being able to revive someone. that is cool.
